The stocks are reacting to a Bloomberg report that was published. According to the report, US officials are reportedly investigating the claims Adani Group made to American investors after a damning study from Hindenburg Research accused the corporation of utilizing offshore firms to covertly manipulate its stock price.

The report also stated, law enforcement agencies frequently initiate inquiries that don't result in action, so requests for information from US prosecutors don't always imply that criminal or civil procedures will be brought. A spokesperson from the Adani Group said that the group is not aware of any subpoenas to investors. “Our various issuers' groups remain confident that the disclosures are complete as disclosed in the relevant issuer offering circulars,” said the spokesperson.

Hindenburg released a report in January accusing the Adani group of using offshore companies to float their share prices and financial results, the report also said that the group had flouted disclosure.
